To check interaction between operating system and your Supermicro H8SML-iF , select one of the suitable operating system ( Unix class OSes are more suitable ) for you and tested on this card , and try to install it as you like your installed components . If it boots successfully , it means that there is an incompatibility between your FreeBSD and the main board . If no one of them boots , then you may conclude that , there is a problem in your settings . BIOS settings are important , because , OS communicates with the main board through these settings . In manual ( downloaded from the above page : Manual Revision 1.0c Release Date: March 12, 2014 ) , page 4-9 , "PCI/PnP Configuration" is defined . If PnP is selected YES. OS adjusts some device settings . If NO is selected , BIOS adjusts some device settings . When BIOS adjusted device settings are not conforming to OS parameters , the result will be "FAIL" . Therefore , more suitable selection is YES . Another point is that , there are many more BIOS selectable parameters and jumpers about PCI slots and others . There are some BIOS settings for PCI slots : PCI X4 Slot 6 ( page 4-9 ) PCI x8 Slot 7 ( page 4-10 ) Please review these BIOS settings in your manual and set them with respect to your requirements .
